Insteadthey went with Solution 2. The resulting currency, known as bitcoin cash, increased the blocksize to 8 Mb in order to accelerate the verification process to permit a performance of around two million transactions every day. At the time of writing, Bitcoin Cash is valued at $545.00 to Bitcoins $6,328.11.
When you hear about bitcoin mining, you envisage coins being dug from the ground. But bitcoin isnt bodily, so why do we call it mining
Because its like gold mining in the bitcoins exist in the protocols design (like the gold exists underground), but they havent been brought out into the light yet (like the gold hasnt yet been awakened ). The bitcoin protocol stipulates that 21 million bitcoins will exist at some point.
They get to do this as a reward for creating cubes of confirmed transactions and including them in the blockchain.
Backtracking a little, lets discuss nodes. A node is a powerful computer that runs the bitcoin software and helps to keep bitcoin running by participating in the relay of information. Anyone can run a node, you just download the bitcoin applications (free) and leave a certain port open (the downside is the fact that it consumes energy and storage space the network at time of writing carries up about 145GB).
One node will send information to some nodes that it knows, who will relay the information to nodes that they know, etc.. This way it ends up getting around the whole network pretty fast. .
Some nodes are mining nodes (usually referred to as miners). These group outstanding transactions into cubes and add them to the blockchain. How can they do this By solving a complex mathematical mystery that is a portion of this bitcoin program, and including the answer in the block. The mystery that needs solving is to find a number which, when combined with the data in the block and passed through a hash function, produces a result that's within a certain range.
How can they find this number By guessing at random. The hash function which makes it impossible to forecast exactly what the outcome will be. So, miners guess the puzzle number and apply the hash function to the combination of that guessed number and the information in the block. The resulting hash has to start with a pre-established number of zeroes.
Whats more, there may be several nonces that produce the desired result, or there may be none (in the event the miners keep trying, but with a different block configuration). read here .
The first miner to get a resulting why not try these out hash within the desirable range announces its victory to the rest of the network. All the other miners immediately stop work on that block and start trying to figure out the mystery number for the next one. As a reward for its work, the victorious miner has some new bitcoin. .
At the time of writing, the payoff is 12.5 bitcoins, which in time of writing will be worth nearly $200,000.
Additionally, the costs of being a mining node are considerable, not only due to the effective hardware needed (if you've got a faster processor than your competitors, you have a better chance of finding about his the right number before they do), but also because of the large amounts of power that running these chips consumes. .
And, the number of bitcoins awarded as a reward for solving the mystery will decrease. Its 12.5 now, but it pits each four decades or so (the next one is expected in 2020-21). The value of bitcoin relative to price of power and hardware could go up over the next few decades to partly compensate this reduction, but its not certain. .
The difficulty of the calculation (the necessary number of zeroes at the beginning of the hash string) is corrected frequently, so that it takes on average about 10 minutes to process a block.
Why 10 minutes that's the amount of time that the bitcoin developers think is necessary for a steady and diminishing flow of new coins until the maximum number of 21 million is attained (anticipated some time in 2140).
